Multifactorial genetic diseases include some of the frequently occurred humandiseases and inherent deformities,such as hypertension,schizophrenia,epilepsy,myo-pia,strabismus,cleft-lip palates,inherent heart diseases,etc.Statistics show thatsufferers of such diseases amount to 12% of the population in China(myopia exclud-ed).Some of these are major lethal causes,hence they affect human health stronglyand deserve attention.In this paper,the mathematical model for calculating the recurrence risks of mul-tifactorial...

Multifactorial genetic diseases include some of the frequently occurred humandiseases and inherent deformities,such as hypertension,schizophrenia,epilepsy,myo-pia,strabismus,cleft-lip palates,inherent heart diseases,etc.Statistics show thatsufferers of such diseases amount to 12% of the population in China(myopia exclud-ed).Some of these are major lethal causes,hence they affect human health stronglyand deserve attention.In this paper,the mathematical model for calculating the recurrence risks of mul-tifactorial genetic diseases is analyzed,and a general method of genetic enquiry usinga computer is described and programmed correspondingly.Based upon statistical data,the risks of cleft-lip palates and strabismus amongChinese are computed with influence of second-degree relatives taken into account,Genetic enquiry tables are listed.Under special conditions,real-time enquiry is possible using another program.The method and program described here also apply to the enquiry for recurrencerisks of any multifactorial genetic diseases.

多基因遗传病包括一些常见的人类疾病与先天畸形,如高血压、精神分裂症、冠心病、癫痫、近视、斜视、唇裂、腭裂、无脑儿、脊柱裂和先天性心脏病等。据统计,上述疾病的患者约占我国总人口的12%以上(不包括近视)。其中有些疾病甚至是致死的主要原因,因此对人类健康影响很大,值得重视。本文分析了计算多基因遗传病发病机率的数学模型,阐述了利用计算机进行遗传咨询的方法,并编制了相应程序。根据我国唇裂、腭裂和斜视的统计资料,进一步考虑了二级亲的影响,对中国人(上海地区)唇裂、腭裂和斜视发病机率进行了计算,并列出了遗传咨询表。对于特殊情况还可通过计算机进行实时咨询。本文所介绍的方法和程序适于咨询任何多基因遗传病的发病机率,为我国开展优生学研究提供了依据。

This essay introduces a variety of methods of inferring hereditary intelligence according to the theory that the development of human intelligence depends synthetically upon many factors including environment education and multi-genetic heredity. It is also necessary to analyse and evaluate their separate effects in psychological and educational studies. The strong points and weak points of different methods are discussed. It is suggested that a synthetic and crcss-reference approach be adopted.

本文根据人类智力发展是由多基因遗传因素与环境、教育因素共同作用的理论,以及在心理学与教育学研究人类智力发展问题时,需要分析和估算这两种因素分别作用的情况,介绍了推测遗传因素在智力发展中的遗传趋势和估算遗传力的各种方法,并分析和指出了各种方法的优缺点,提出了在实际研究中,应将这四种方法综合应用、相互参照的意见。

Geographic variation in leaf size and shape of the widespread and environ mentally-tolerant indigenous shrub Leptospermum scoparium (Myrtaceae) was determined from 182 herbarium specimens collected over much of its natural range. There were significant correlation with geographic and climatic factors-latitude, distance from coast, annual and winter temperatures. Seven teen seedling populations raised in a uniform environment showed that this leaf variation had a significant genetic component as did the variation in form and the age at first flowering. Ecotypic differentiation is therefore clearly indioated in L. scoparium.

Leptospermum scopoarium(Myrtaceae)是一个颇为多变的种,新西兰人常称之为manuka,从半匍伏状灌木到高达12米的乔木,为新西兰木本植物区系中分布最广泛,环境忍耐力最强,因而最丰富的种类。遍布两个主要岛屿——北岛和南岛,远及北面的Three Kings岛(34°10′S),东到Chatham岛,南达Stenart岛(47°S)。根据采自新西兰全国各地的182份L.scoparium标本,对其叶片大小和形态的地理学变异进行了研究。这些变异与地理因子和气候因子有着显著的相关性。Morrison和Myerscough(1982)发现悉尼地区的L.flavescens的叶片特点和环境有着类似的相关性,但他发现的相关性只涉及到土壤类型。而未研究气候的变化。虽然土壤对L.scoparium的变异是重要的。但很多变异是随地理学趋势发生的。从体现本种广泛的自然分布区中,选择17个种群的种子,栽种在同一环境下,用以评论了表型成分和遗传成分对在叶型和植物形态的几个方面的变异性的相对作用。所测定的幼苗的7个特征反映了明显的遗传成分,特别表现于叶的形态,野外标本与由采自同一位置的种子产生的幼苗非常相似...
